Given data from the table.
Total possible outcomes = 4 + 3 + 6 + 4 + 2 + 6 + 2 + 3 = 30
Number of required outcomes (Freshman) = 4 + 3 = 7
[tex]\begin{gathered} \text{Probability of an event = }\frac{N\text{umber of required outcomes}}{N\text{umber of total posible outcomes}} \\ =\text{ }\frac{7}{30} \\ In\text{ percentage} \\ =\text{ }\frac{7}{30}\text{ }\times\text{ 100\%} \\ =\text{ }\frac{700}{30} \\ =\text{ 23.33\%} \\ =\text{ 23\% } \end{gathered}[/tex]
